To all whom it ma 1 concern:

Be it. known that we, THOMAS DAIXS WILLIAMS. and WILLIAW GREENWOOD, ofOldham, in the. county of Lancaster, England, have invented certain newand useful Improvements in Underclear rs or Flukers for Spinning and'lwisting Machines, of which the following is a specification.

In connection with spinning and twisting machines, underclearers orllukers are applied for the purpose of keeping the bottom rollers freefrom waste cot ton and by taking up broken ends to prevent them fromwrapping round the delivery rollers. It is usual to drive theumlerclearers by mounting them in frictional contact with the bottomrollers. This method is subjectto defects chief among which is theinsufficient clearing action of the underclearer resulting in theproduction of lappers and bad ends.

\Vhen the underclearer is supported in direct contact with the bottomfluted roller, the said underclearer runs. as a matter of necessity, atthe same surface speed as the fluted roller. The waste sliver thereforewraps around the underclearer in exactly the same state as it leaves thenip of the upper leather roller and the bottom fluted roller ofthespinning frame. This tends to cause the sliver to wrap tightly aroundthe underclearer and the accumulating sliver is made to assume a still.more hardened and compressed form upon the underclearer, due entirelyto the fact that the said undcrclearer is in direct contact with thefluted roller.

In order to obviate the defects mentioned, we drive the undercleareis ina special manner as will now be described.

Of the accompanying drawings: Figure 1 is a front OlOVittlOll of so muchof the rollers of a ring frame as is necessary to show our invention.Fig. 2 is a sectional side elevation on line -.EF in Fig. 1. Fig. 3 is asectional view of a complete ring. Fig. 4 is a front elevation of onehalf of a ring.

In carnving out our invention, we mount upon the bottom fluted roller.at intervals, rings, rollers, or bosses A. The rings or rollers can bemade of wood, fiber, india rubber or metal, preferably the latter, and

they act as drivers for the underclearers or flukers G. \Ve preferablymount two rings upon each section or length of the bottom fluted rollerB. By the use of the rings A the miderclearers C are caused to travel atl a greater surface speed than the bottom rollers. In consequence of theuuderclearer running at a greater surface velocitv than from the mainsliver passing between the rollers is attenuated and in consequence madethinner and softer. It is this attenuated sliver that is taken up by theunderclearer although, in our constructiom said underclearer does notrotate in contactwith the bottom fluted roller. 'Iherefore nocoinpressing or hardening, of the waste sliver results, and owingdirectly to this, the operative can remove the waste sliver from theunderclearer without having to resort to a metal picker as hasheretofore been done.

Since the waste which the umlerclearers take up is more loosely woundaround their periphery than formerly, and is consequently more easy toremove, not only are metal pickers rendered unnecessary, but ourinvention also minimizes the production of bad ends, lappers {MK riders,and makes piecing up easier and facilitates the production of betterpiecings.

As the sliver passes through the three pairs of rollers of a spinningframe, it moves in an almost horizontal direction as opposedto a.circular direction. When the sliver emerges from the nip of the lastpair of rollers it will, if it be free, follow this horizontal directionfor an appreciable distance, and then curl inward and follow thecircular travel of the rollers. In consequence of this feature of thetravel of the waste slivers, it is )ossiblc for a roller set slightlybelow the ottom fluted roller to take up the waste sliver. Moreover, anumber of fibers project quite sufficiently from the outside of anuntwlstcd sliver from the surface of a fluted roller.

The distance between the bottom fluted roller B and the umlerclcarer Cin our construction is only a slight one, but it is suffi cient for thepurpose stated. This distance is determined by the thickness of therings, rollers, or bosses A which, as indicated in Figs. 3 and 4, maycomprise two metal half rings fastened on the fluted roller wherercquired, by means of screws D.

Having now described our invention, what we claim is:

The combination with a bottom fluted roller and the under-clearer of aspinning and does the bottom fluted roller, the fiber taken I sliver toenable a roughened surface to at tract them and to draw the whole of theIUD clearer, the said underclearer being out of contact with the flutedportion of the roller, the said rings being of greater diameter than thefluted portions of the roller to drive the underolearer at a greatersurface speed than the fluted portion of skid roller.

twisting machine, of driving rings mounted In testimony whereof we have.aifixed our on said fluted roller and engaging the undersignatures, inpresence of two w1tnesses THOMAS DAINS WILLIAMS. WILLIAM GREENWOOD.
